Tech firms have largely been spared the recent onslaught of sexual harassment allegations, but reports of the legendary “bro” culture continue to surface.

Amid the seemingly daily revelations of improper behavior, sources recently told The Post that on an autumn day in 2015, a trio of Snap execs were overheard discussing their weekend plans — which included ordering up prostitutes — while on a partnerships conference call with a well-known digital media company.

The Los Angeles-based tech bros must have thought they were on mute, according to our tipster, because they began to detail their party plans among themselves, but did not realize that someone from the media company had already dialed into the call and was waiting on the line.

The dudes — part of middle management — began talking about hookers before they were interrupted.

“It was gross,” said an insider with knowledge of the conversation.

When asked if the guys could have been joking around, the source shot back: “It sounded like they were serious.”

When the bros realized their plans had been overheard, they seemed “embarrassed,” according to our source.

The call then proceeded as normal as the guys chatted about how the media brand could work with Snapchat on partnerships for its Discover platform.

A source said that the pervy call was never brought to the attention of Snap higher-ups at the time, due mainly to the “shocking” nature of the whole thing, “This reported behavior is completely unacceptable at Snap and is not reflective of our culture and values,” a Snap spokesperson said. “We are looking into these allegations,” said a Snap spokesperson.
